Definitions
- the Schlieren stops 17A, 17B, and associated optics 15A, 15B, 16A, 16B are employed, as before, to remove zero or first orders from the two modulated, pulsed beams emergent from the cells 12A, 12B, and the modulated, pulsed beams are re-combined using an image combiner 32 such as a dichroic mirror, thence being projected via a projection lens 34 and the scanning mirror 18.
